Dogmaus: It's my pleasure! I'm about to play it myself!
MarkoH01: I have finished the game now (all three routes) and really had a great time. It's hard to believe but while the minimalistic artstyle could scare some people away the game is actually quite creative and has some really nice ideas and puzzles in it. Sometimes you have different possibilities to solve puzzles and those might completely change other aspects of the game. This game are actually three games (or at least two since the neutral and bad route are not THAT different) because of three different ways to solve it (leadin to three different endings as well). Thank you once again. :)
I have only reached the bad ending, alas, I hope to do better in the next games in the series! I can say I find the graphic style appealing for its underground and disturbing esthetics. I am glad that you enjoyed it.
